Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WATMS4

The SPMWHT541MP5WATMS4 is the qualified substitute for the obsolete SPMWHT541MD5WATMS3. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts operate at identical forward voltage (2.95V) and test current (65mA). The substitute delivers 33 lumens versus 31 lumens at the same operating point, representing a 6.5% luminous flux increase. Efficiency improves from 162 lm/W to 172 lm/W. Both maintain 80 CRI and 120° viewing angle, ensuring color rendering and beam characteristics remain consistent with the original design.

Mechanical Compatibility: Both components use the 5630 package footprint with identical 5.00mm × 3.00mm dimensions. The substitute height of 0.80mm is lower than the original 0.90mm, providing improved clearance margins in space-constrained applications. Thermal resistance remains constant at 16°C/W.

Regulatory & Supply Status: The SPMWHT541MP5WATMS4 carries Active product status with ROHS3 compliance, compared to the Obsolete status of the original part. This ensures long-term availability and regulatory alignment. Both parts maintain MSL 2A (4 Weeks) moisture sensitivity classification.

Maximum Current Rating: The substitute supports 180mA maximum current versus 150mA for the original, providing additional operational headroom for designs requiring higher current operation.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WATMS4 be used as a direct replacement in existing designs?

A: Yes. The SPMWHT541MP5WATMS4 is electrically and mechanically compatible with the SPMWHT541MD5WATMS3. Both parts share identical forward voltage, test current, viewing angle, and CRI specifications. The 5630 package footprint and dimensions are identical, enabling direct PCB substitution without layout modifications.

Q: What are the differences in luminous output between these parts?

A: At the standard test current of 65mA, the SPMWHT541MP5WATMS4 produces 33 lumens compared to 31 lumens for the SPMWHT541MD5WATMS3. This 2-lumen difference (6.5% increase) falls within typical manufacturing tolerance ranges for LED products and does not require circuit redesign. Efficiency improves from 162 lm/W to 172 lm/W.

Q: Are there packaging differences between these parts?

A: Both parts use the 5630 surface mount package with 4-SMD configuration. The original features a flat lead with exposed pad, while the substitute uses flat leads. Both maintain identical 5.00mm × 3.00mm footprint dimensions. The substitute is 0.10mm lower in height (0.80mm vs. 0.90mm), which is advantageous for space-constrained designs.

Q: What is the significance of the product status change from Obsolete to Active?

A: The SPMWHT541MP5WATMS4 carries Active product status, indicating Samsung Semiconductor maintains ongoing production and supply. This eliminates obsolescence risk and ensures long-term component availability for production and field service applications.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS compliant. The original part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status, representing an updated regulatory classification. Both maintain identical MSL 2A (4 Weeks) moisture sensitivity levels and ECCN EAR99 export classification.

Q: Can the substitute handle higher current applications?

A: Yes. The SPMWHT541MP5WATMS4 supports a maximum current rating of 180mA compared to 150mA for the original part. This provides additional operational margin for designs requiring higher current operation, though standard operation remains at 65mA test current for both parts.

Q: Are there thermal performance differences?

A: No. Both parts maintain identical thermal resistance of 16°C/W, ensuring equivalent thermal management characteristics in circuit designs.
